Actually, that I know of, the P-51D had a retractable tail wheel, and it was a Single-engine, Single-seat Escort and Air Superiority Fighter, or as Fighters were called back then, Pursuit aircraft. Either way, incredible model! the design of the rudder, for example is simple, yet effective. This plane has fully-movable control surfaces and a fully retracting landing gear--very impressive. I give it a 5/5.
